Polynomial Regression Network for Variable-Number Lane Detection

no code implementations ECCV 2020 Bingke Wang, Zilei Wang, Yixin Zhang

Most of previous methods utilize semantic segmentation to identify the regions of traffic lanes in an image, and then adopt some curve-fitting method to reconstruct the lanes.

Revisiting Foreground and Background Separation in Weakly-supervised Temporal Action Localization: A Clustering-based Approach

1 code implementation ICCV 2023 Qinying Liu, Zilei Wang, Shenghai Rong, Junjie Li, Yixin Zhang

It comprises two core components: a snippet clustering component that groups the snippets into multiple latent clusters and a cluster classification component that further classifies the cluster as foreground or background.

Convolutional Neural Networks Rarely Learn Shape for Semantic Segmentation

no code implementations11 May 2023 Yixin Zhang, Maciej A. Mazurowski

Shape learning, or the ability to leverage shape information, could be a desirable property of convolutional neural networks (CNNs) when target objects have specific shapes.

Class Relationship Embedded Learning for Source-Free Unsupervised Domain Adaptation

no code implementations CVPR 2023 Yixin Zhang, Zilei Wang, Weinan He

To this end, we first regard the classifier weights of the source model as class prototypes to compute class relationship, and then propose a novel probability-based similarity between target-domain samples by embedding the source-domain class relationship, resulting in Class Relationship embedded Similarity (CRS).

Low-confidence Samples Matter for Domain Adaptation

1 code implementation6 Feb 2022 Yixin Zhang, Junjie Li, Zilei Wang

Representing the target data structure in such a way would overlook the huge low-confidence samples, resulting in sub-optimal transferability that is biased towards the samples similar to the source domain.

Probabilistic Contrastive Learning for Domain Adaptation

2 code implementations11 Nov 2021 Junjie Li, Yixin Zhang, Zilei Wang, Keyu Tu, Saihui Hou

However, it is undesirably observed that the standard contrastive paradigm (features+$\ell_{2}$ normalization) only brings little help for domain adaptation.
